A liquid crystal display screen is an optical device made from tiny liquid crystal matter sandwiched between two glass plates. LCD screens are commonly used in smart phones, laptops and computer monitors. The downside to most LCD screens is that the liquid crystal matter is fragile and can cause the screen to break or scratch easily. Fortunately, you can repair scratches on your LCD screen yourself without any technical experience.

  1. 1

    Power off your computer monitor, laptop or mobile device. Allow the device to cool down for a few minutes before attempting to repair scratches on the LCD screen. If the screen is hot, you can actually cause more damage.

  2. 2

    Wipe down the screen's surface with a damp eyeglass polishing cloth. This removes all dust and debris from the surface of the screen. What appears to be a scratch, could just be dust or dirt build up on the screen.

  3. 3

    Wipe down each scratch on the LCD screen's surface with the damp eyeglass polishing cloth.

  4. 4

    Apply a generous amount of petroleum gel to a cotton swab. Gently apply to the scratched areas of the screen. The general idea is to fill the scratch with the gel so it is no longer noticeable. Allow several minutes for it to dry.

Tips and warnings

  • Make sure you are dealing with a scratch, and not a crack. If the screen is cracked all the way through, the screen must be replaced. Contact a local computer repair technician for professional diagnostics.
